`TCP_NODELAY` disables Nagle’s algorithm, which is generally a better
default for modern networks than having it enabled. Nagle’s algorithm
delays sending small data blobs until they fill an entire TCP segment,
so as to amortise the cost of sending the segment.
This improves bandwidth at the cost of latency. Given the large
bandwidth capabilities of most modern networks, most streams are
constrained by latency rather than bandwidth, so disabling Nagle’s
algorithm makes sense.
Various other major bits of software (such as libcurl) already disable
Nagle’s algorithm by default.
Specific applications which need it can turn it back on by calling
`g_socket_set_option()`.

`P_()` is for pspec strings — it gave us the option to split them out to
a separate translation domain. `_()` is for normal strings.

Nicks and blurbs don't have any practical use for gio/gobject libraries.
Leaving tests untouched since this features is still used by other libraries.

Previously these properties would have been documented using the strings
from the pspec, but those will be removed in the following commit. Re-add
the documentation using those strings, but as gi-docgen documentation
comments.

The `#include <langinfo.h>` in `gdatetime.c` is currently predicated on
`HAVE_LANGINFO_TIME`, but it’s needed for all the `HAVE_LANGINFO_*`
features.
It seems the code implicitly assumes that `HAVE_LANGINFO_TIME` will be
true if any other `HAVE_LANGINFO_*` macros are true. While I haven’t
seen this assumption be broken in practice, it seems prudent to
explicitly encode that in the configure tests. It’s easy enough to do.

The changes in commit 95479256df didn’t
completely work (or some other change has broken them since): the
informational message at the end of the script is now not printed.
Fix that by stopping bash exiting immediately if the subshell exits, by
using it in a boolean expression.

It was previously set (by default) to `C`, so this commit doesn’t change
the locale behaviour of the tests, but does ensure that messages printed
by the tests are correctly formatted in UTF-8 rather than transliterated
to ASCII.
That makes interpreting test output easier.

The `%E` modifier causes dates to be formatted using an alternative era
representation for years. This doesn’t do anything for most dates, but
in locales such as Thai and Japanese it causes years to be printed using
era names.
In Thai, this means the Thai solar calendar
(https://en.wikipedia.org/wiki/Thai_solar_calendar). In Japanese, this
means Japanese era names
(https://en.wikipedia.org/wiki/Japanese_era_name).
The `%E` modifier syntax follows what’s supported in glibc — see
nl_langinfo(3).
Supporting this is quite involved, as it means loading the `ERA`
description from libc and parsing it.
Unit tests are included.

Fixes: #3119
GDBus has always supported matching strings with arg0 matching
(`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH`). In D-Bus 1.5, support was added
to the spec for also matching object paths. This got forgotten about and
was never added to GDBus, meaning that
`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH` won’t match against a signal arg0
of type `o`.
Fix that, and add a unit test.
To do so, we need to add a new `g_dbus_message_get_arg0_path()` API to
complement the existing `g_dbus_message_get_arg0()` API. The approach of
letting `g_dbus_message_get_arg0()` return an object-path *or* a string
would not work, as it’s also called in the implementation of
`G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_NAMESPACE`, which must only match
string-typed arg0 values and not object-path-typed ones.

Technically we can’t rely on it being kept alive by the `message->body`
pointer, unless we can guarantee that the `GVariant` is always
serialised. That’s not necessarily the case, so keep a separate ref on
the arg0 value at all times.
This avoids a potential use-after-free.
